FIFA World Cup 2026: Scientists Warn of Extreme Heat Risks in Host Cities
A group of international scientists has raised concerns about the heat safety measures planned for the FIFA Men's World Cup 2026, set to take place in the United States, Canada, and Mexico. In an open letter, experts in health, climate, and sports performance criticized FIFA's current guidelines as inadequate and misaligned with modern scientific understanding. They highlighted the potential for extreme heat stress in 14 of the 16 host stadiums, particularly in southern U.S. and northern Mexican cities, where daytime temperatures often exceed 86°F (30°C) and can approach 104°F (40°C) during heatwaves. The scientists are urging FIFA to implement stronger protections, such as extended cooling breaks and clearer protocols for delaying or rescheduling matches under extreme conditions. FIFA has responded by affirming its commitment to player and staff safety, stating that climate risks are being considered in tournament planning.
